Replaceable Membrane H Type Electrochemical Cell Jacketed Split Electrolysis Cell for Laboratory Research

Product Overview

This advanced electrochemical cell system provides an optimized three-electrode architecture, separating the reference and working electrodes into distinct chambers to drastically reduce IR drop. Integrated with a high-precision Luggin capillary, the design prevents cross-contamination of electroactive species between the anode and cathode, ensuring pristine analytical environments. The chamber isolation is maintained through a secure, high-integrity membrane clamping system, enabling reliable transport investigations and clean cyclic voltammetry experiments.

Perfect for state-of-the-art research in carbon dioxide reduction, nitrogen fixation, water splitting, and electrocatalyst evaluation, this system serves academic laboratories, material sciences divisions, and industrial energy research departments. The physical configuration allows researchers to seamlessly switch between different types of ion exchange membranes, supporting a broad spectrum of aqueous and organic electrolyte evaluations.

Built using premium-grade borosilicate glass paired with custom CNC-machined fluoropolymer seals, the equipment guarantees exceptional chemical inertness and mechanical stability. It delivers consistent, reproducible voltammetry data under highly acidic, basic, or high-temperature experimental conditions. Researchers can operate with complete confidence, knowing that the system avoids potential leakage or crossover contaminants during long-duration runs.

Key Features

• Precision Luggin Capillary Integration: The integrated Luggin capillary extends directly into the working electrode chamber, featuring an ultra-fine tip aperture of less than 0.2 mm. This configuration places the potential sensing point extremely close to the working electrode surface, minimizing uncompensated ohmic resistance (IR drop) in low-conductivity electrolytes. The inner channel of the capillary can also be loaded with agar gel to regulate electrolyte flow velocity, stabilizing the reference potential throughout long-duration experiments.
• Replaceable Membrane Partition: The system features a modular split-chamber architecture. A heavy-duty chain clamp acts as the securing interface, allowing researchers to easily insert and swap ion exchange membranes (such as Nafion or custom polymeric membranes). The tension is distributed evenly across the glass flanges, ensuring an airtight seal without risking thermal or mechanical stress fractures to the borosilicate structure.
• 360-Degree Rotating PTFE Inserts: The alignment of electrodes is crucial for uniform current distribution. The working and counter electrode chambers employ external threads and a rotating PTFE inner core, enabling precise 360-degree alignment of the electrode surfaces parallel to the membrane. The assembly is secured using robust, chemically resistant Polyoxymethylene (POM) outer caps, providing a gas-tight, reliable seal.
• Refined Reference Electrode Isolation: The reference electrode chamber utilizes specialized internal threads. When sealed, it blocks liquid movement between chambers driven by the communicating vessel effect (siphoning). This isolates the reference electrolyte, eliminating contamination and reference potential drift.
• Versatile Sub-Surface Gas Purging: Sub-surface aeration is optimized via customized glass spargers. A straight-type sparger is provided for carbon reduction (CO2RR) to maximize CO2 saturation, while an L-shaped sparger is used for nitrogen reduction (NRR) to maintain proper gas flow geometry relative to the electrode surface.
• Thermal Management via Double-Jacketed Design: For temperature-dependent electrocatalysis, the jacketed cell version allows circulating fluids (water or silicone oil) to pass through a vacuum-insulated outer glass sleeve. This keeps the internal electrolyte at a constant temperature, reducing thermodynamic variance in kinetics studies.
• Premium Material Composition: Every wet component is fabricated from either high-durability borosilicate glass 3.3 or high-purity PTFE. Borosilicate 3.3 features low thermal expansion and extreme resistance to chemical attack. PTFE inserts are CNC machined to tight tolerances to prevent any leachables or trace contaminants from compromising experimental data.

Why Choose This Product

• Precision Craftsmanship & Performance Reliability: Every unit is manufactured using precision CNC-machined fluoropolymers and master glassblowing techniques. This ensures absolute structural symmetry, dimensional consistency, and tight tolerances that prevent any physical leaks or potential measurement deviations.
• Advanced Fluid and Charge Dynamics: The combination of the micro-aperture Luggin capillary and parallel-aligned electrodes ensures highly uniform electric field lines and minimal ohmic loss, allowing researchers to capture precise reaction kinetics without the interference of massive IR drops.
• Versatile Customization Capabilities: KINTEK offers customization of chamber volumes, auxiliary sampling ports, and electrode sizes. We can modify the design to include absolute sealing valves for oxygen-sensitive or volatile reaction monitoring, adapting perfectly to your specific experimental goals.
• Superior Sealing Technology: The multi-threaded design, combined with compression O-rings and POM outer caps, guarantees an airtight seal that withstands positive pressures during purging. This minimizes the leakage of volatile organic solvents or high-purity reaction gases.
• Unmatched Chemical Inertness: By using high-grade borosilicate glass 3.3 and virgin PTFE, the system remains completely non-reactive to corrosive acids, strong bases, and organic solvents, eliminating the risk of trace contamination in sensitive analytical studies.
